Came across this paper (actually a chapter from a larger work) that was published back in 2017. Was doing an internet search and my keywords proffered this as a search result. This paper covers a bit about the early geology of the landmass that became the state of Florida but contains a more in depth look at the climate and geology over the last 50 Ma. It is not a very long read and contains some interesting graphics. I'd recommend this as fundamental reading for any Florida resident interesting in geology and fossil hunting. A really nice concise background into the geology of our state that due to its location and elevation has been very susceptible to ocean level changes throughout its history. https://floridaclimateinstitute.org/docs/climatebook/Ch15-Hine.pdf Cheers. -Ken

Travel back to when the Chesapeake Bay was first formed to learn about the geologic history of the region: https://www.chesapeakebay.net/discover/ecosystem/bay_geology Of note are the role a meteor crater played, and the estimation that Calvert Cliffs have eroded west about 300 ft. in the last 400 years.

"rising Sea Level" Conference, Parrsboro, Nova Scotia - Oct. 19Th
redleaf101 posted a topic in Members' News & Diversions
Hi guys! Anybody on the East Coast, the Fundy Geological Museum in Parrsboro, Nova Scotia, is hosting a conference on "Rising Sea Level: The Impact on Coastal Communities along the Bay of Fundy", held this coming Friday October 19th. My friend Ken Adams, whom I've had the luck to accompany on many of his geological walks of the Cumburland area, had made past remarks on the ever changing landscape, the pace of erosion, and intriguing points. Here's the FGM's summary from their website: http://museum.gov.ns...conference.aspx Cheers! Keenan- 1 reply
